CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 225,578, dated March 16, 1880. ll

- 'Application filed December 13, 1879. 1

To all whom it may concern: Be it known that 1, ORLO H. DRINKWATER of Cedar Point, in the county of Chase and State of Kansas, have invented a new and useful Improvement in OarUouplings and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is an improvement in automatic car-couplings; and it consists in the construction and arrangement of parts, as

. hereinafter described, and as shown in accompanying drawings, in which a Figure 1 is a side View, and Fig.2 a plan view, of the coupling; Fig. 3, an end view.

A represents a draw-head having the usual construction, when adapted for use, of the common link-and-pin coupling. My improved coupling devices are attached to said drawhead, and consist chiefly of two parts, to wit:

a convex detachable head, B, having lateral extensions or horns and a clevis or link, 0, which is pivoted to the draw-head and adapted to swing laterally. The said horned head B is arranged horizontally, and has a tenon, b, which enters the recess of the draw'head A, and is secured therein by a pin, 0. The link or clevis Q is also preferably pivoted on the same pin 0, and swings in a horizontal plane. It is held, normally, nearly in line with or parallel to the axis of the draw-head A by means of a spring, D, and the stay-pin E. The latter passes vertically through the middle of the detachable head B, and the spring presses the clevis 0 against the pin, and only holds it in contact with the same, as shown in full lines, Figs. 1 and 2, except in the operation of coupling two cars, in which case the front end of the clevis comes in. contact with the convex head B, attached to the opposite car, and slides laterally on the same, thus passing around able for the purpose, but do not deem it necessary to illustrate the same in this instance. The link 0 is made wide enough at its front end to adapt it to couple cars of unequal height.

I propose in some cases to construct the convex head B integral or solid with a drawbar, A, in place of making it detachable, as

shown; but by the above-described construction I am enabled to apply my automatic coupling to the draw-heads or bumpers now in use without requiring any change or modification of its construction.

To adapt the head B for use with the ordinary link it is provided with a recess, 0, in its front end, and the pin E passes vertically through the same, as shown.

In place of the plate-spring D, I may employ a spiral spring, and apply it so as to connect the clevis to the stop-pin E.

- I am aware draw-heads have been provided with fixed and detachable horns and convex heads, and with hinged links or bails for en gaging the same. I do not, therefore, claim such combination of parts.

What I claim is-- In a car-coupling, the combination of the spring and stay-pin, the swinging link, and the head B, as shown and described.
